R ggplot2-如何在相同的x值上绘制2个箱形图

Question

假设我有两个箱型图。

trial1 <- ggplot(completionTime, aes(fill=Condition, x=Scenario, y=Trial1))
trial1 + geom_boxplot()+geom_point(position=position_dodge(width=0.75)) + ylim(0, 160)

trial2 <- ggplot(completionTime, aes(fill=Condition, x=Scenario, y=Trial2))
trial2 + geom_boxplot()+geom_point(position=position_dodge(width=0.75)) + ylim(0, 160)

我如何在相同的地块和相同的X上绘制试验1和试验2？ 它们的y范围相同。

我看了geom_boxplot（position =“ identity”），但是在同一X上绘制了两个条件（填充）。

我想在同一X上绘制两个y列。

Answer 1

您可以尝试使用interaction来结合两个因素，并针对第三个因素进行规划。 例如，假设您要按原始代码中的条件进行填充：

library(tidyr)
completionTime %>% 
gather(trial, value, -Scenario, -Condition, -User) %>%
ggplot(aes(interaction(Scenario, trial), value)) + geom_boxplot(aes(fill = Condition))

结果：
